Specification of Letters Patent. I Patented-Aug. 6, 1918.

Application filed September 30, 1914. Serial No. $154,212.

To all whom it may concern:

Be 'it known that I, Bmir K. Form, a citizen of the United States, residing in' Oak and has more particular reference to conprovement in Container-Closures, of which tainers for ether-and other highly explosive volatile liquids.

Ether and he like mustbe-handled' with great care because of its well known anesthetic effect and because also of its high explosive power andhigh co-eliicient of expansion. It is used for an anesthetic by being poured in a relatively small amount of gauze held in a wire frame or mask which is placed over the mouth and nose of the subject. From time to time more other is added to the maskin order that the subject may be maintained in desired and anesthetized condition. It is extremely volatile and must be kept between the times that it is applied, as described, hermetically sealed from the atmosphere. This hermetic sealing should be done without the use of solder or the like by reason of the extremely high explosive power of ether.

It'is a principal object of this invention to provide a container closure which can be opened and closed without the use of opening tools orimplements and which may be hermetically sealed by merely turning the parts to closed position.'

It is a further object of this invention to provide a closure of the character described,

of simple and durable construction, capable of easy operation'and of inexpensive production.

Other objects and advantages of the invention will be apparent as it is better understood from the following description when considered in connection with, the

accompanying drawing illustrating a pre ferred embodiment thereof.'

Referring to the drawin s, Figure 1 is a side elevation of a container embodying my invention;

member. 1

For the purpose of illustrating my invention I have shown it embodiedin anether Y present invention and may have any usualor preferred construction; the top 10, however, being provided .with an enlarged central aperture 12 for the reception of the closure 11. I I

The closure 11 consists in the present instance of a pressed threaded neck 13 secured at its lower end at 14 in the opening 12. A- partition 16 formed preferably integraLwith the neck 13 is provided across the bottom of the neck and this partition is provided I with a central perforation 15, the material 151 of the partition about this opening being deflected upwardly fora purpose which will be hereafter disclosed. A combined stopper I and spout member comprising a valve member or stopper of lead, cork or other soft material 17- having a recess in its top. and

perforated longitudinally as seen at 18, be=

neath said recess, the perforations 18 being disposed about the center of sa1d stopper and out of vertical alinement with'the per-.

foration 15 in the partition, and a spout member 19, is provided to fit within the neck 13.

The spout member is preferably formed of a sheet of suitable metal, tin being well adapted for this purpose. metal is formed to provide oppositely extending spouts 20 and 21 communicating with each other and forming a passageway extending across the top of, the container,

This sheet of.

and portions 22 of the sheet are bent about the stopper 17 as shown in Fig. 7, these por-' tions being pressed to form threads adapted to engage threads formed on the stopperand to engage also the threadsof the neck 13.

- The centrally disposed opening is of apa hermetic seal.

propriate dimension to permit it to be tightly closed by the central imperforate portion of the stopper 17 when the stopper is turned inwardly intoengagement with the partition 16. The imperforate portion of this cork or'the portion at its center serves to close the perforation 15 in the partition 16 so that a gas and liquid tight seal is pro vided. The upwardly deflected edge about the opening 15 cuts into the material of the stopper at each closing operation and forms When it is desired to use the contents of the container it is only necessary to turn. the spout member 19, and through the spout member the stopper, to move the parts from the closed position shown in Fig. 2 tothe open position shown in Fig. 3, lifting of thestopper bringing the apertures 18 into communication with the perforation 15. If the container be tilted with the parts arranged in this position the contents .will run through the perforation 15, apertures 18 and out through the lower spout 20 or 21. The flow of this liquid can be controlled by closing with the finger the upper spout. The container-may be filled or re-filled. with ether or other, liquid by merely removing the stopper entirely and pouring the material into the then open neck. The recess in the stopper 17 is merely for the purpose of lightening it ifa heavy alloy of metal be used. I

The stopper-member is preferably formed from a single piece of metal as has been stated, and'this piece may be cut to the shape of the blank shown in Fig. 5 in which the two oppositely. extending relatively short and narrow Wings 23 are subsequently to form the spouts 21 and 20 and the two wings 24: are to form the portions 22 embracing the cork 17. This blank is bent by being placed in a suitable die into the shape shown in Fig 6 or so that all of the wings are given a semi-circular form. Partial threads 25 and 26 are formed in the two widerwings 24 by pressing the blank in suitable dies, the f threads 25 in one wing 24 being pressed to coiiperate with threads 26 formed in the other wing 24 to form a continuous thread 27 when the stopper or spout member is completed. .With form shown in Fig. 6

complete the two rounded spouts 20 and 21.

It will be manifest that a containerembodying this invention may becheaply constructed that it may .be metically sealed for shipment and readily unsealed for use and that the container may be readily controlled in its delivery ofliquid and may be easily and quickly closed after tending the blank pressed into the its only necessar to J bend the two wings 24 about the cork l to complete the structure, the edges'28 of each wing 23 coming together-to the interior strongly and herarges? each use without the need of special tools or ap liances. I

. t is thought that the invention and many of its attendant advantages-willbe understood from the foregoing without further description, and it Will be obvious that various changes may be made both in the form, construction and arrangement of the parts and in the manner of making and as'sembling them without departing from the spirit and scope of the lnventlon or sacrificmg any of its material advantages, the form.

hereinbefore described being merely a preferred embodiment thereof.
